Selecting the Download Code button displays the Download Code

screen.

• The box to the right of Scanner Firmware displays the firmware

version on the upgrade diskette (if inserted in the drive) and the

version presently installed in the Scanner. This button must be

selected, and a valid upgrade diskette must be in the floppy disk

drive, before the Begin button can be selected.

• Once the software detects that a valid upgrade disk is present, the

message changes to : "Select the Begin button when you are ready

to proceed." The Begin button becomes selectable.

• Selecting the Begin button Installs the new version. Once the

upgrade process has started, It must be allowed to complete.

CAUTION

Ensure that power Is maintained to the Scanner and

SIM/XPC during the upgrade process, and that the

process is allowed to terminate normally. Any

interruption of the upgrade process results in the

unrecoverable corruption of the firmware memory in the

Scanner, requiring replacement of the Control PWB.

Several blocks of code are downloaded and verified. The screen shows

each block that is downloaded. When the process Is complete, the

Scanner reboots, and the flashing message "Warming Up" is displayed.

This message disappears when the reboot process is complete. The

version number displayed in the Installed box is now the same as the

version on the upgrade disk.

The Exit button returns to the Main Diagnostic Menu screen.

After downloading a new version of the scanner firmware, check the

following adjustments:

• Calibrate Document Registration (ADJ 4.1.2)

• Front to Back Stitch (ADJ 4.1.3)

• Left to Right Stitch (ADJ 4.1.4)
